Geology of the eastern Bering Sea continental shelf
The Bering Sea shelf south of the Bering Strait encompasses an area of 1,300,000 km2, more than the combined area of California, Oregon, and Washington (840,000 km2, Fig. 1). The shelf area lies between western Alaska and eastern Siberia. The outer shelf is underlain by three large basins, Bristol, St. George, and Navarin, filled with sedimentary rocks, as well as by three bedrock ridges that extend from the Alaska Peninsula to near Siberia (Figs. 1 and 2). The innermost part of the shelf, Norton Sound, is underlain by the large, sediment-filled Norton basin (Fig. 1; Fisher and others, 1982). A similar inner basin, Anadyr basin, underlies the Gulf of Anadyr along the western side of thee Bering shelf (Fig. 1).
Figures & Tables
You get a comprehensive overview of the geology, tectonic evolution, and mineral resources of Alaska and adjacent areas of the continental margin. Plates include state-wide maps showing geology, physiography, lithotectonic terranes, metamorphic rocks, igneous rocks, sedimentary basins, isotopic age data, neotectonics, isostatic gravity, magnetics, and metallic mineral deposits. Summaries of bedrock geology and geologic history are given for eleven large regions of Alaska and adjacent offshore areas. Twenty topical chapters synthesize data on metamorphic and igneous rocks; major onshore and offshore sedimentary basins; the paleomagnetics evidence for latitudinal displacements and rotations, glacial history and periglacial phenomena; and the occurrence, evolution, and potential of Alaska's vast resources of petroleum, coal, and metallic minerals. A summary chapter provides an overview and presents a possible model for Alaska's Phanerozoic evolution. The Geology of Alaska is the largest publication produced in the Decade of North American Geology program, a fitting tribute to this magnificent area.
